LFR is going to be great. People complain it will probably be too easy, since it's going to be scaled down even lower then normal difficulty, but who cares? The loot won't be as good either. That's part of the tradeoff.
I was peaking around the PTR files and the Deathwing fight looks insane based on what I have found.
They made a version of his model that is so huge that part of his back is the playable area, and you literally fight on his back pulling away his armor, all the while his "defense systems" in his body are fighting you, like magma blood elementals. They also made a new skybox that "flips" for the times he does a barrel roll to try and shake you off.
When you defeat him he crashes into the Maelstrom and his body just starts to melt. He takes up the whole Maelstrom in a fight similar to Kil'jaeden, where he pulls himself out and casts at you from the middle. From what I can tell he hold himself up using what's left of his arms and wings, which are now basically magma tentacles. Once you destroy those you attack his body and kill him off for good, making him sink into the Maelstrom.
All I can say is that without a raid guild, the fact I will be able to easily PuG these fights sounds awesome. I just want to experience them more then worry about loot.
